IMPROVEMENT IN COMBINED FIRE-PLACE DAMPER-PLATE AND ARCH-BAR.

Specification forming part of Letters Patent No. 222,697, dated December16,- 1879; application filed June 30, 1879. i

Plate and Arch-Bar Combined; and I do hereby declare that the followingis a full, clear, and exact description of the invention, which willenable others skilled in the art to which it appertains to make and usethe same, reference being had to the accompanying drawings, and toletters of reference marked thereon, which form a part of thisspecification.

The object of my invention is to provide a simple and effective devicefor regulating the draft of smoke-fines in fire-places ofdwellinghouses, close the same entirely when not in use, to prevent thefalling of soot into the room, and also serve the purpose of an arch barto sustain the brick-wall over the fireplace opening.

To this end it consists of a metallic plate or frame having aflue-openin g through its center, the frame constructed somewhat largerthan the fire-place opening, over which it is placed, so that it willhave suitable bearing on the jambs and back wall, said plate havingstrengthening-ribs cast upon the upper surface, and provided with anadjustable lid or damper to close the flue-opening in the plate, all ofwhich I will now proceed to describe indetail, reference being had tothe drawings, in which Figure 1 is a perspective view of a chimneybreastwith a portion cut away, showing my device in position over thefire-place. Fig. 2 is a top view of the damper and arch-bar; Fig. 3, across-section on line 00 w, and Fig. 4 a-lengthwisc section of theplate.

Like letters of reference refer to like parts. A represents a .platemade, preferably, of cast-iron, of suitable size to cover over thefire-place opening, having strengthening'ribs a a a on the uppersurface, which serve a double purpose of a frame or guides to inclosethe movable damper and prevent the plate from warping. b b are arch-barribs cast on the front edge of the plate, as shown. The rib b is placeda shortdistance from the front rib, such ribs being adapted to sustainthe weight of the wall above the fire-place.

O is a narrow oblong slot or flue-opening through the plate A,proportioned in size to suit the fire-place. B is a damper-plate,resting on the plate A between the ribs a a,"havin g strengthening-rib(1 cast around its edge, and provided with indents e c on the lowerside, near the front ed ge, to permit of theplate being moved over theflue-opening from below with the aid of the hand or some suitableinstrument. E E representethe jambs of the fire-place.

While I show the damper B as separate from and sliding on the surface ofthe plate A between the guides a a. over the flue-opening O, yet Iregard it within the scope of my invention to pivot said damper at eachend to the plate A, so it will revolve in the fine-opening, or .hingeone side of the damper to the edge of the flue-opening, so that it'maybe raised or lowered, as required.

I also consider it within the scope of my invention to attach aconnecting-rodto the damper, extending through the wall, for thepurpose'of operating the same; but for general purposes I find that themovable damper B, adjusted by means of the hand, answers every purposeand gives satisfaction.

By casting the arch-bar ribs 1) b on the plate A the labor of buildingan arch across the fire-place opening to sustain the wall above isavoided, there being, besides, the additional advantage of having thearch -bars and plate combined in one article of manufacture.

With the useof my invention I avoid the necessity of closing thesmoke-flue with straw or other like material when the fire is withdrawnin the spring of the year to prevent the soot from falling into theroom. By simply drawing the damper over the flue-openingI prevent alldanger and trouble from soot or fire from adjoining flues.

Having described my invention, what I claim, and desire to secure byLetters Patent,

1. In a fire-place, the plate A, cast with arch-bars for supporting thewall above the fire-place, as set forth.

2. The combination, with a fire-place, of the I In testimony that Iclaim the foregoing as plate A, cast with arch-bars, and having fluemyown I hereunto afiix my signature in pres opening 0 and adjustabledamper B, substanenoe of two Witnesses.
